AP-I is a high performance digital measurement equipment for locating the alignment and depth of buried underground cables and pipelines. By adopting the most recent microcomputer and digital correction technologies, AP-I simply gets its work done with accurate and consistent results.

Built for Quality - Low MTBF

AP-I is built for practical intensive use on site, with very low MTBF (Mean Time Between Failure). This reduces interruption to project and working progress.

• High accuracy up to 2.5%
• Triple depth detection up to 12m
• Maximum 10W high signal power output
• Dual frequency transmission for best results in inconsistent situation
• Automatic impedance coupling for best signal transmissions
• 4 antenna design
• Differential coils technology to reduce interference
• Search and select of best suited frequency in radio mode
• Depth reference in Radio and Power mode
• Current measurement display with depth
• Integrated backlight for night works
• Error protection function
• 100% design and made in Japan

Data logging

• data logging for up to 400 points
• record number display, helping on site marking and paper records
• data and time stamp (real time clock)
• quick one touch operation
